Dr. Weiss delicately handling the female noting the unusual coloring on this female.

Creekside biologists were enthused to find a female Bay Checkerspot adult on Tulare Hill today. The siting of this female brings hope that critical habitat for this rare butterfly still exists and that the population is still holding on, if not barely, at this location. Tulare Hill has undergone some significant habitat improvements through well executed stewardship. The site shows great potential for serving as a protected refugia for Bay Checkerspots as well as other South Bay serpentine endemics.
